Name

tex1Dcmplod - performs a texture lookup with a specified level of detail and a shadow compare in a given sampler.

Synopsis

float4 tex1Dcmplod(sampler1D samp, float4 s)
float4 tex1Dcmplod(sampler1D samp, float4 s, int texelOff)

int4 tex1Dcmplod(isampler1D samp, float4 s)
int4 tex1Dcmplod(isampler1D samp, float4 s, int texelOff)

unsigned int4 tex1Dcmplod(usampler1D samp, float4 s)
unsigned int4 tex1Dcmplod(usampler1D samp, float4 s, int texelOff)

Parameters

samp

Sampler to lookup.

s

Coordinates to perform the lookup. The value used in the shadow comparison should be passed right after the normal coordinates. The level of detail corresponds to the last component of the coordinate vector.

texelOff

Offset to be added to obtain the final texel.

Description

Performs a texture lookup with shadow compare and a specified level of detail in sampler samp using coordinates s.

Profile Support

tex1Dcmplod is supported in fragment profiles starting with fp40 and in vertex profiles starting with vp40. Variants with texelOff are only supported in gp4 and newer profiles. Variants with integer samplers are also only suppported in gp4 and newer profiles.
